SPECIFICATION forming part of Letters Patent No. 507,007, dated October 17, 1893.

Application filed June 27, 1892. Serial No. 438,169. (No model.)

To K1/ZZ whom it may concern/.-

Be it known that we, JAMES HOLMES and KARL PETERSON, citizens of the United States, residing at Jamestown, in the county of Chautauqua and State of New York, have invented a new and useful Wood-Carving Machine, of which the following is a specification. f

This invention relates to carving machines, and has special reference to that class of maj chines wherein the tools are held stationary as to adjustment, and supported over a universally movable table on which the work is placed, and consists of the construction, arrangement, and combination of the parts thereof as a whole and in detail, as will be more fully hereinafter described and claimed.

The object of the present invention is to provide mechanism for supporting the work which is freely movable and adapted to duplicate carvings, and to produce a true copy of the same from a pattern, through the medium of a stationary guiding tool moving over said pattern, and produce a similar result on material held on the table of the device and under the carving tools.

In the drawingsz-Figure 1 is a perspective View of the improved machine. Fig. 2 is a transverse vertical section taken through the center thereof. Fig. 3 is a central longitudinal section of the same. Fig. et is a sectional elevation of a portion of the mechanism broken away in parts and on a large scale. Fig. 5 is a plan view of a part of the mechanism,`broken away in parts. Fig. 6 is a section on the line .fn-, Fig. 1. Fig. 7 isa sectional elevation showing an attachment for holding the table stationary when arrang;v ing the work thereon. Fig. 8 is a detail per.- spective view of an attachment.

Similar numerals of reference are employed to indicate corresponding parts in the several figures.

Referring to the drawings, the numerals 1 and 2 designate uprights or corner posts of the frame which are connected by parallel longitudinally disposed base bars 3, and transverse connectingbarst. The'upperpor; tion of the `said uprig`hts or corner posts are connected by a rear longitudinal beam 5, and a front spindle beam 6', the latter being Aformed preferablyofy Ushaped channeled iron or other material.v C l Between and supported by the two posts 2 is a driving shaft 7, which carries a driving pulley 8 and a series of flanged band pulleys 9. The pulleys 9 are suitably positioned and have belts 10 running therefrom and to hori.

zontally disposed pulleys ll, surrounding or carried by the spindles l2 of the carving tools, which depend below the said spindle beam 6 a suitable distance. In the center of the said beam 6, is the guiding spindle 13, to which the guiding tool or tracer is fastened. As seen in Fig. 6 each of the spindles 12 is surrounded by a split bushing 14, on which bears and is mounted a pulley 1l, and held in connection therewith by a set screw 15. To enable each of the spindles 12 to be adj usted, the said construction is employed, and also preserve the spindle against scratching or marring, by having the said set screw 15 bear against the bushing let and still provide the requisite clamping connection. The said spindles are made adjustable verticallyr in order that they may be adapted for use in carving various thicknesses of Wood. Boxes or journals 17, are adjustably mounted in openings 18, in the flanges of the beam 6 and surround each of the spindles, and are adapted to have their ends bear against the bushing 14 to hold the pulley in the proper adjusted position. The said boxes or journals are formed With flanged outer ends or heads 19,

which prevent the same from moving entirely through the openings 18, and provide a limitation or stop for the same, and when said boxes or journals'are properly adjusted they are sustained in such adjustment by means of horizontally disposed set screws 20, extending inward from the edges of the iianges of the beam 6, and bearing thereagainst. The belts 10 pass over the pulleys 9 in vertical planes, and where said belts pass around the Spindle pulleys 11 they assume a horizontal position, whichis made necessary by the position of said spindle pulleys.

Extending transversely across the beams 3 and projecting beyond the same are beams 21, on which are supported rails 22 adapted to be engaged by grooved rollers 23 carried by transverse cross beams 24, the latter being connected by beams 25, and the said beams 24 and 25 form a base frame or support, from the corners of which vertically rise an- IOC gnlancornerposts 26. The saidiangular `corner posts 26 comprise two flanges 27, eachlof which has yokes 28 mounted in connection therewith in vertical alignment, and pro" vided with screw Shanks 29, which extend through-openings'30 in thef-said angestofl the corner posts and are held in position by nuts 31, which engage the said screw :shanksg and bear against the outer sides of the said flanges. The said yokes 28 carry anti-fric-V tional` rollers 32, which bear against a-trian-E gular shaped post 33. One of the said posts 33 is arranged in connection`with"each f' thei corners of the frame just set forth, and the i5 Mksaidf'anti-frictional rollers 32 bear'agai-nst the 'outer faces of the same which are arranged" ati1 right angles= to each other. iTotheupper ends of each of t-he posts-33 *issecureda table 34, 'which is made Llonger.. 2o* than itis broad or 4of substantially rectangular fform, anid to= the lower portion ot'` eachof ther =saidfpo"sts is bolted the 'outer end of an=-arm;` "35,asfsho'wn morefnlly at 36inlFig. 4.

the sides of the table 55. By this means the said table 55 may be held rigid while the work Vand pattern are being adjusted thereon, and when the said yoke is not in use, it is turned upward as shown in dotted lines in Fig. 7, and held in said positionrby a turn screw or hook 70 connected to the upper portion of the. spindle beam 6.

A bracket 7l is secured to one of the posts 26, and extends upward at an angle ofinclination, having formed at the free end there` of jaws 72, and an opening 73 extending through the center of the same. The said jaws V72 are adapted to receive and embrace a depending end bracket 74, which has au opening 75 therein adapted to align with the opening 7 3 of the bracket 7l for the purpose of receiving a clamping bolt and nut 76, which holds the two brackets detachably connected with each other. A

On the bracket 74 is secured a rest or board 77 by means of abolt 7 8,'which passes through This construction is shown in Fig. 8, and only one end thereof is illus'- trated,as the opposite portion of the same is a duplicate of that which has already been described. Both of the bolts 76 2and 78 are mounted in slots, as the opening 75 is'elongated and thereby'provides for the vertical adjustment of the'bracket 74. In like manner'the bolt 78 is fitted in a slot 79 which may be made of any suitable length and thereby arranges for an endwise adjustment of the rest or board 77. The object of this construction is to provide arest for the operator when moving the table 55, and it also acts as a convenient means for moving the mechanism connected to the table 55, and thereon may be placed tools, Wrenches and other devices employed in thework of carving.

In operation, the table is held rigid by the attachment illustrated in Fig. 7, the work is placed in proper position together with the model or pattern, the guiding tool held bythe guiding spindle is adjusted so that it will touch the highest point'on'the pattern, and the carving tools adjusted by lowering thespindles, so that they will touch the boards or pieces of wood to be carved. One board may be of one inch thickness and the others more or less.

This done, the attachment is turned up and mechanism set forth, the table may be moved in any manner desired, as when any varying thicknesses, or rounding off, in the pattern, as in relief or raised carving, the said table may be simultaneously moved horizontally and vertically, that is obliquely or at anyfangle desired; horizontally, by the casters 5 6 rolling on the'tables 34, and vertically by the posts 33, carrying tables 34, sliding between' the rollers 32, the saidposts being connected by arms `35, which are supported by counterbalancing weights and levers, as set forth. The slatted construction of the table 55 also provides for the positioning of suitable clamps 8O for holding the work in position, which may be passed between the said slats and are of any preferred form of construction. The rollers 23 carried by the end cross/beams 24, and in connection with the operating and supporting mechanism of the table 55, provide for an adjustment of all the parts supported by the said rollers outwardly, as may be required, when the work to be carved is of greater length than the width of the plates 34, so that it may be properly and successfully manipulated. Y

The parts of the framework of the device set forth may be constructed of any suitable material and in any preferred form, which will be best adapted for the proper support of the mechanism.

The advantages of the device set forth will be readily apparent to thosel skilled -in the art, and need not be further, enlarged upon herein.

By means of the knife or scale edges in connection with the parts set forth, a Very vsensitive construction is provided which will respond to the slightest adjustment with exceptional beneficial results,'as will be seen. y
